CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 202210781228.3, filed with the China National Intellectual Property Administration on Jul. 4, 2022, and entitled “VAPORIZATION CORE FOR E-CIGARETTE, CARTRIDGE FOR E-CIGARETTE, AND E-CIGARETTE”, the entire contents of which are incorporated herein by reference.

FIELD

The present disclosure relates to the field of e-cigarette technologies, and more specifically, to a vaporization core for an e-cigarette, a cartridge for an e-cigarette, and an e-cigarette.

BACKGROUND

As the control and restrictions on tobacco become more stringent around the world, e-cigarettes, as a substitute for conventional tobacco, can not only simulate the sensory experience of smoking, but also cause far less damage to health than the conventional tobacco, which makes the demand for e-cigarettes increase year by year.

The e-cigarette usually includes a cartridge and a cigarette rod. The cartridge is mounted on the cigarette rod and can produce smoke to be inhaled by the human body. The cartridge has an e-liquid storage cavity, an airway, a vaporization cavity, and a vaporization core. A vaporization liquid for generating smoke is provided inside the e-liquid storage cavity. The vaporization liquid is heated and vaporized by the vaporization core to form smoke, and the smoke enters the vaporization cavity, and then is inhaled by the user through the airway.

In the related art, when users inhale e-cigarettes, phenomena such as “e-liquid frying” or “burnt core” often occur, which seriously affects the taste of the smoke.

SUMMARY

The present disclosure is intended to resolve at least one of the technical problems in the related art. Therefore, embodiments of the present disclosure are to provide a vaporization core for an e-cigarette. The vaporization core is assembled in the e-cigarette. During inhalation of a user, a vaporization liquid can be fully vaporized, which reduces the phenomenon of “e-liquid frying” in the e-cigarette, and can avoid the phenomenon of “burnt core” during inhalation of the user, making the taste of the smoke purer.

The present disclosure further provides a cartridge for an e-cigarette having the foregoing vaporization core for the e-cigarette.

The present disclosure further provides an e-cigarette having the foregoing cartridge for the e-cigarette.

According to an embodiment in a first aspect of the present disclosure, a vaporization core for an e-cigarette is provided, including: a liquid guide body, where the liquid guide body has a first side surface and a second side surface arranged opposite to each other, at least a part of the first side surface forms a liquid absorbing region, at least a part of the second side surface forms a vaporization region, the liquid guide body includes a liquid storage portion, the liquid storage portion is a part of the liquid guide body between the second side surface and a position obtained by translating the second side surface to the first side surface by 0.5 mm to 1.5 mm, a liquid storage amount of the liquid storage portion is Q1, and quality of vaporization liquid vaporized by the vaporization core in one inhalation cycle is defined as a single-inhalation vaporization amount T1, where T1≤Q1≤3T1; and a heating body, where the heating body is arranged at the vaporization region of the second side surface.

It has been found in the research process that, the reason for the phenomenon of “e-liquid frying” or burnt core that occurs during inhalation of the e-cigarette in the related art is that: after the vaporization liquid in the liquid storage cavity of the e-cigarette enters the vaporization core, a part of the vaporization liquid cannot be fully vaporized, and gathers in a non-vaporization region of the vaporization core, and the non-vaporization region of the vaporization core will also be heated by the heating body, but it is insufficient to vaporize the e-liquid, resulting in “e-liquid frying”. During inhalation of the user, this part of the vaporization liquid will be inhaled into the user's mouth along with the smoke, which seriously affects the taste of the smoke. In the related art, there is also a phenomenon that the vaporization liquid transmitted to the vaporization region is insufficient, resulting in “burnt core”, which will also seriously affect the taste of the smoke.

It has been further found through research that a temperature of a part between a side surface of the liquid guide body close to the vaporization region and a position obtained by translating the side surface to a side surface facing the liquid absorbing region by 0.5 mm to 1.5 mm can reach a vaporization temperature of the vaporization liquid, that is, can reach an effective vaporization temperature of the vaporization liquid. This part of the liquid guide body is defined as the liquid storage portion, and other parts are defined as a liquid guide portion. By controlling the liquid guide amount of the liquid guide portion, when the liquid storage amount of the liquid storage portion and an amount of the vaporization liquid vaporized by the vaporization core in one inhalation cycle meet a certain relationship, it can be ensured that the vaporization liquid is fully vaporized and the vaporization amount is stable, and problems such as “burnt core” can be prevented. It has been found through research that when the liquid storage amount Q1 of the liquid storage portion and the vaporization liquid vaporized by the vaporization core in one inhalation cycle, that is, the single-inhalation vaporization amount T1, meet: T1≤Q1≤3T1, the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette can be effectively solved.

In the description of the present disclosure, “a plurality of” means two or more.

A cartridge 100 for an e-cigarette according to an embodiment of the present disclosure is described below with reference to accompanying drawings.

As shown in FIG. 1 to FIG. 15 , the cartridge 100 includes a housing 4 and a vaporization core 200 for the e-cigarette according to the following embodiment of the present disclosure.

The housing 4 has a liquid storage cavity 41, an airway 43, and a vaporization cavity 42, and the vaporization cavity 42 is in communication with the airway 43, and the housing 4 has an air inlet 44 in communication with the vaporization cavity 42 and an air outlet 45 in communication with the airway 43. The vaporization core 200 is arranged inside the housing 4.

The vaporization core 200 for the e-cigarette according to this embodiment of the present disclosure is first described with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 15 , the vaporization core 200 for the e-cigarette according to this embodiment of the present disclosure includes a liquid guide body 1 and a heating body 2.

The liquid guide body 1 has a first side surface 11 and a second side surface 12 arranged opposite to each other. It can be understood herein that the first side surface 11 and the second side surface 12 are arranged opposite to each other, and the first side surface 11 and the second side surface 12 are not limited to being necessarily parallel. At least a part of the first side surface 11 forms a liquid absorbing region, and at least a part of the second side surface 12 forms a vaporization region. The liquid guide body 1 includes a liquid storage portion 14. The liquid storage portion 14 is a part of the liquid guide body 1 between the second side surface 12 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm.

It should be noted that a distance between a boundary surface (shown by dashed lines in FIG. 4 , FIG. 5 , and FIG. 7 ) of the liquid storage portion 14 and the second side surface 12 is 0.5 mm to 1.5 mm. Apart between the second side surface 12 and the boundary surface is defined as the liquid storage portion 14, and a shape of the boundary follows that of the second side surface 12. That is, if the second side surface 12 is a curved surface, the boundary surface is a curved surface (shown in FIG. 4 and FIG. 5 ); and if the second side surface 12 is a flat surface, the boundary surface is a flat surface (shown in FIG. 7 ). Certainly, the second side surface 12 and the boundary surface may be constructed as surfaces in other shapes. In other words, regardless of the shape of the second side surface 12, the liquid storage portion 14 has a volume defined by the translation of the second side surface 12 toward the first side surface 11 by 0.5 mm to 1.5 mm.

In addition, the first side surface 11 may be constructed as a surface in a different shape, for example, a flat surface shown in FIG. 4 , or a curved surface shown in FIG. 5 .

The liquid storage amount of the liquid storage portion 14 is Q1, and quality of a vaporization liquid vaporized by the vaporization core 200 in one inhalation cycle is defined as a single-inhalation vaporization amount T1, where T1≤Q1≤3T1. Further, 1.2T1≤Q1≤2.3T1. For example, Q1/T1 is 1, 1.5, 2, 2.5, or 3. The heating body 2 is arranged at the vaporization region of the second side surface 12.

It should be noted that the single-inhalation vaporization amount T1 is the quality of the vaporization liquid consumed in one inhalation cycle. In addition, the liquid storage portion 14 may be a part of the liquid guide body 1 between the second side surface 12 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

An example is used to illustrate the test method of the single-inhalation vaporization amount. The single-inhalation vaporization amount is usually measured according to GB41700-2022, where the inhalation duration specified by “single-inhalation” is (3.0±0.1) seconds, and the total inhalation flow is (55±0.6) ml. A glass fiber filter is used to collect e-cigarette emissions, and the glass fiber filter before and after inhalation is separately weighed on an analytical balance with a sensitivity≤0.1 mg. The quality difference is the single-inhalation vaporization amount, and a unit thereof is mg.

The liquid absorbing region of the first side surface 11 is in communication with the liquid storage cavity 41, and the liquid absorbing region can absorb the vaporization liquid from the liquid storage cavity 41, so as to facilitate the vaporization of the vaporization liquid in the e-cigarette. The vaporization region of the second side surface 12 is in communication with the vaporization cavity 42.

According to the vaporization core 200 for the e-cigarette in this embodiment of the present disclosure, by arranging the heating body 2 at the vaporization region of the second side surface 12, that is, after the vaporization liquid absorbed by the liquid absorbing region penetrates to the surface of the vaporization region, the vaporization liquid is heated by the heating body 2 to form smoke (which includes, but not limited to, aerosol, suspended liquid, low-temperature vapor, and volatile gas), and the smoke enters the vaporization cavity 42. When the user inhales the e-cigarette, the external air enters the vaporization cavity 42 and is mixed with the air in the vaporization cavity 42 to be inhaled by the user.

According to the vaporization core 200 for the e-cigarette in this embodiment of the present disclosure, it has been found that phenomena such as “e-liquid frying” and “burnt core” in the related art is caused by mismatching between the quality of the vaporization liquid consumed by the vaporization core in each inhalation process (that is, the single-inhalation vaporization amount) and the quality of the vaporization liquid that can be fully vaporized by the vaporization core.

Based on this, it is first conceived of calculating the single-inhalation vaporization amount. It has been found in a large quantity of experiments and researches that an average time for a user to inhale an e-cigarette each time is 3 seconds, and an average amount of vaporization liquid that needs to be consumed for each inhalation of the e-cigarette by the user is about 5 ml to 10 ml.

In addition, based on the above, after in-depth research, it has been found that a temperature of a part of the liquid guide body 1 between the second side surface 12 and a position obtained by translating the second side surface 12 (which is the surface on which the vaporization region is arranged) to the first side surface 11 by 0.5 mm to 1.5 mm is greater than 180° C., and the temperature of this part is an effective vaporization temperature. That is, the vaporization liquid stored in this part can be fully vaporized, and this part of the liquid guide body 1 is defined as the liquid storage portion 14.

Further, after conducting further research on the relationship between the liquid storage amount of the liquid storage portion 14 and the phenomenon of “e-liquid frying”, it has been found that when the liquid storage amount of the liquid storage portion 14 is 1 time to 3 times of the single-inhalation vaporization amount, not only the vaporization liquid in the liquid storage portion 14 can be fully vaporized, the vaporization liquid vaporized in the liquid storage portion 14 can match the single-inhalation vaporization amount, to effectively solve the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette.

In this way, the amount of e-liquid stored in the vaporization core 200 and the quality of the vaporization liquid consumed during a single inhalation can not only ensure that the vaporization liquid is sufficient to ensure the amount of vapor output, but also can avoid a case that the vaporization liquid is excess and cannot be fully vaporized, to prevent that unvaporized vaporization liquid penetrates into parts other than the vaporization region and gathers, which causes phenomena such as “e-liquid frying” and “burnt core”. Therefore, it is ensured that the demand for inhalation is met, e-liquid leakage is prevented, and the user experience is improved.

Therefore, the vaporization core 200 for the e-cigarette according to this embodiment of the present disclosure can match the single-inhalation vaporization amount, thereby ensuring the amount of vapor output, and ensuring that the vaporization liquid is fully vaporized.

The cartridge 200 for the e-cigarette according to this embodiment of the present disclosure uses the vaporization core 100 for the e-cigarette according to the foregoing embodiment of the present disclosure, which can match the single-inhalation vaporization amount, thereby ensuring the amount of vapor output, and ensuring that the vaporization liquid is fully vaporized.

According to some specific embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid storage amount of the liquid storage portion 14 is 5 mg to 30 mg, and the calculation method of the liquid storage amount Q1 of the liquid storage portion 14 satisfies: a volume of the liquid storage portion 14×a porosity of the liquid storage portion 14×a density of the vaporization liquid, where the density of the vaporization liquid is the density of the e-liquid conventionally used in the field of e-cigarettes, which is usually 1.05 kg/m³ to 1.2 kg/m³. For example, the liquid storage amount of the liquid storage portion 14 may be 6 ml to 28 ml, 8 ml to 25 ml, 10 ml to 23 ml, 12 ml to 21 ml, 14 ml to 19 ml, and 15 ml to 17 ml, such as 5 ml, 10 ml, 15 ml, 20 ml, 25 ml, or 30 ml.

As one of the embodiments of the present disclosure, as shown in FIG. 8 , the calculation method of the volume of the liquid storage portion 14 satisfies: an area of the second side surface 12×a height of the liquid storage portion 14, where the height of the liquid storage portion 14 refers to a dimension of the liquid storage portion 14 in an extending direction from the second side surface to the first side surface. In this embodiment, the area of the second side surface 12 is equal to a product of a length of the second side surface and a width of the second side surface.

In this embodiment, both the liquid guide portion 13 and the liquid storage portion 14 are porous ceramic bodies, and the liquid guide portion 13 and the liquid storage portion 14 have a same porosity, the measurement method of the porosity of the porous ceramic body is a conventional measurement method in the art. For example, the measurement method of the porosity of the porous ceramic body may be based on the test method for the apparent porosity of porous ceramics in GBT1966-1996.

In this way, the vaporization liquid in the liquid storage portion 14 can be fully vaporized, so as to be matched with the single-inhalation vaporization amount, to effectively solve the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , in one inhalation cycle, an inhalation time of the vaporization core 200 is 2.9 s to 3.1 s, and a total inhalation flow thereof is 54.4 ml to 55.6 ml, where the total inhalation flow is a sum of an air flow and a smoke flow. In this way, it helps to ensure the concentration of the smoke and the total amount of the smoke during each inhalation, which helps to ensure the taste and improve the user's inhalation experience.

In addition, the single-inhalation vaporization amount T1 is equal to 5 mg to 10 mg. In other words, in each inhalation process, the vaporization liquid is consumed by 5 mg to 10 mg. The single-inhalation vaporization amount is more adapted to the vaporization amount required by the user, so that the inhalation demand of the user can be met, and the vaporization amount will not be excessively large to cause waste of the vaporization liquid.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm; and a liquid guide amount D1 of the liquid guide portion meets: 0.5T1≤D1≤1.2T1.

In other words, the liquid guide amount of the liquid guide portion 13 is 0.5 times to 1.2 times of the single-inhalation vaporization amount. Further, the liquid guide amount D1 of the liquid guide portion meets: 0.8T1≤D1≤1.0T1. For example, the liquid guide amount of the liquid guide portion 13 is 0.5 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, 0.10 times, 1.1 times, or 1.2 times of the single-inhalation vaporization amount.

The liquid guide portion 13 can lengthen a path of the liquid guide body 1 for absorption and penetration of the vaporization liquid, and increase the amount of vaporization liquid used for vaporization. The liquid guide portion 13 may be a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

After each inhalation of the user, the vaporization liquid in the liquid guide portion 13 will be replenished to the liquid storage portion 14, and the liquid guide amount of the liquid guide portion 13 will be 0.5 times to 1.2 times of the single-inhalation vaporization amount. The vaporization liquid in the liquid guide portion 13 can be replenished into the liquid storage portion 14 in time to prepare for next inhalation of the user, and the liquid guide portion 13 can be prevented from replenishing excess vaporization liquid into the liquid storage portion 14.

For example, the calculation method of the liquid guide amount of the liquid guide portion 13 is: a liquid guide speed of the liquid guide portion 13×an area of the liquid absorbing region×the inhalation time in one inhalation cycle (for example, 3 S)×the density of the vaporization liquid, where a density of the e-liquid conventionally used in the field of e-cigarettes with the vaporization liquid usually is 1.05 kg/m³ to 1.2 kg/m³.

According to this embodiment of the present disclosure, as shown in FIG. 8 , the area of the liquid absorbing region is equal to an area of the first side surface 11, and is equal to a product of a length of the first side surface 11 and a width of the first side surface 11.

An example is used to illustrate the test method of the liquid guide speed of the liquid guide portion 13. A dry liquid guide portion 13 to be tested with a height of h is fixed on a fixture to keep horizontal, and each generatrix of the liquid guide portion 13 is ensured to be vertically upward. Two to three drops of e-liquid are quickly dripped at the center position above the liquid guide portion 13, and a time t from a moment at which the e-liquid is just in contact with an upper region of the liquid guide portion 13 to a moment at which the e-liquid just permeates to a lower part the liquid guide portion 13 is recorded, where t/h is the liquid guide speed of the measured liquid guide body, and a unit thereof is mm/s.

In this way, the liquid guide amount of the liquid guide portion 13 can meet the replenishment demand for the liquid storage amount of the liquid storage portion 14. By controlling the liquid guide amount of the liquid guide portion 13, the liquid storage amount of the liquid storage portion 14 can match the single-inhalation vaporization amount, which can not only ensure that the vaporization liquid is fully vaporized, and the vaporization amount is stable, but also ensure that the e-liquid in the liquid guide portion 13 can be replenished to the liquid storage portion 14 in a timely and appropriate manner. That is, the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette can be effectively solved.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 to a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm. The liquid guide amount of the liquid guide portion 13 is 2.5 ml to 12 ml. For example, the liquid guide amount of the liquid guide portion 13 is 2.5 ml, 3 ml, 3.5 ml, 4 ml, 4.5 ml, 5 ml, 5.5 ml, 6 ml, 6.5 ml, 7 ml, 7.5 ml, 8 ml, 8.5 ml, 9 ml, 9.5 ml, 10 ml, 10.5 ml, 11 ml, 11.5 ml, or 12 ml.

The liquid guide portion 13 can lengthen a path of the liquid guide body 1 for absorption and penetration of the vaporization liquid, and increase the amount of vaporization liquid used for vaporization. The liquid guide portion 13 may be a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

For example, the calculation method of the liquid guide amount of the liquid guide portion 13 is: the liquid guide speed of the liquid guide portion 13×the area of the liquid absorbing region×the inhalation time in one inhalation cycle (for example, 3 S)×the density of the vaporization liquid, where the density of the vaporization liquid is 1.05 kg/m³ to 1.2 kg/m³.

In this way, the liquid guide amount of the liquid guide portion 13 can meet the replenishment demand for the liquid storage amount of the liquid storage portion 14. By controlling the liquid guide amount of the liquid guide portion 13, the liquid storage amount of the liquid storage portion 14 can match the single-inhalation vaporization amount, which can not only ensure that the vaporization liquid is fully vaporized, and the vaporization amount is stable, but also ensure that the e-liquid in the liquid guide portion 13 can be replenished to the liquid storage portion 14 in a timely and appropriate manner. That is, the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette can be effectively solved.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm. A liquid storage amount Q2 of the liquid guide portion 13 meets: Q2/Q1=0.5 to 2.5.

For example, the calculation method of the liquid storage amount Q2 of the liquid guide portion 13 is: the volume of the liquid guide portion 13×the porosity of the liquid guide portion 13×the density of the vaporization liquid, where the vaporization liquid is an e-liquid conventionally used in the field of e-cigarettes. For example, the density of the e-liquid is generally 1.05 kg/m³ to 1.2 kg/m³.

According to one of the embodiments of the present disclosure, as shown in FIG. 8 , the calculation method of the volume of the liquid guide portion 13 satisfies: the area of the first side surface 11×the height of the liquid guide portion 13, where the height of the liquid guide portion 13 refers to a dimension of the liquid guide portion in an extending direction from the first side surface 11 to the second side surface 12. In this embodiment, the area of the first side surface 11 is equal to a product of the length of the first side surface 11 and the width of the first side surface 11.

In this embodiment, both the liquid guide portion 13 and the liquid storage portion 14 are porous ceramic bodies, and the liquid guide portion 13 and the liquid storage portion 14 have a same porosity, the measurement method of the porosity of the porous ceramic body is a conventional measurement method in the art. For example, the measurement method of the porosity of the porous ceramic body may be based on the test method for the apparent porosity of porous ceramics in GBT1966-1996.

In this way, the liquid guide amount of the liquid guide portion 13 can meet the replenishment demand for the liquid storage amount of the liquid storage portion 14. By controlling the liquid guide amount of the liquid guide portion 13, the liquid storage amount of the liquid storage portion 14 can match the single-inhalation vaporization amount, which can not only ensure that the vaporization liquid is fully vaporized, and the vaporization amount is stable, but also ensure that the e-liquid in the liquid guide portion 13 can be replenished to the liquid storage portion 14 in a timely and appropriate manner. That is, the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette can be effectively solved.

In addition, a liquid guide amount of the liquid guide portion 13 is D1, where D1≤Q2≤3D1. In this way, a ratio of the liquid guide amount of the liquid guide portion 13 to the liquid storage amount thereof can meet the replenishment demand for the liquid storage amount of the liquid storage portion 14. By controlling the ratio of the liquid guide amount of the liquid guide portion 13 to the liquid storage amount thereof, the liquid storage amount of the liquid storage portion 14 can match the single-inhalation vaporization amount, which can not only ensure that the vaporization liquid is fully vaporized, and the vaporization amount is stable, but also ensure that the e-liquid in the liquid guide portion 13 can be replenished to the liquid storage portion 14 in a timely and appropriate manner. That is, the problems such as “e-liquid frying” or “burnt core” during inhalation of the e-cigarette in the related art that seriously affect the inhalation taste of the e-cigarette can be effectively solved.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm; and the liquid guide portion 13 and the liquid storage portion 14 are separate pieces or an integral piece.

By dividing the liquid guide body 1 into a liquid guide portion 13 and a liquid storage portion 14, the liquid guide portion 13 and the liquid storage portion 14 can be integrally formed to reduce processing difficulty. In some embodiments, the liquid guide portion 13 and the liquid storage portion 14 are arranged separately, and the structures of the liquid guide portion 13 and the liquid storage portion 14 are more diverse, which improves the applicability of the liquid guide body 1 and takes both costs and vaporization efficiency into account.

The liquid guide portion 13 can lengthen a path of the liquid guide body 1 for absorption and penetration of the vaporization liquid, and increase the amount of vaporization liquid used for vaporization. The liquid guide portion 13 may be a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm. Materials of the liquid guide portion 13 and the liquid storage portion 14 are the same or different.

The liquid guide portion 13 can lengthen a path of the liquid guide body 1 for absorption and penetration of the vaporization liquid, and increase the amount of vaporization liquid used for vaporization. The liquid guide portion 13 may be a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

By dividing the liquid guide body 1 into a liquid guide portion 13 and a liquid storage portion 14, the liquid guide portion 13 and the liquid storage portion 14 may be made of different materials. The liquid guide portion 13 may be made of a material with high liquid absorption capacity, and the liquid storage portion 14 may be made of a high-temperature-resistant material.

In some embodiments, the liquid guide portion 13 and the liquid storage portion 14 are made of a same material, but the parameters such as cross-sectional areas, volumes, heights, or shapes of the liquid guide portion 13 and the liquid storage portion 14 are different, thereby improving the applicability of the liquid guide body 1, and taking both costs and vaporization efficiency into account.

In some embodiments of the present disclosure, in order to ensure the structural strength and the high-temperature-resistant performance of the liquid storage portion 14, the liquid storage portion 14 may be set as ceramic. For example, the liquid storage portion 14 is formed by one or more porous ceramic members. In order to improve the vaporization liquid absorption and penetration efficiency of the liquid guide portion 13, the liquid guide portion 13 may be ceramic. For example, the liquid guide portion 13 is formed by one or more porous ceramic members. The liquid guide portion 13 and the liquid storage portion 14 may be an integrally formed whole porous ceramic body.

In some embodiments, the liquid guide portion 13 and the liquid storage portion 14 may be e-liquid absorbing cotton. For example, the liquid storage portion 14 is formed by one or more pieces of e-liquid absorbing cotton, and the liquid guide portion 13 is formed by one or more piece of e-liquid absorbing cotton. The liquid guide portion 13 and the liquid storage portion 14 may be integrally formed, so that the costs are low and the mounting space is small.

In some embodiments, one of the liquid guide portion 13 and the liquid storage portion 14 is ceramic and the other is e-liquid absorbing cotton, and the e-liquid absorbing cotton may be bonded to the ceramic. For example, the liquid guide portion 13 is jointly formed by one or more porous ceramic members and one or more pieces of e-liquid absorbing cottons, and the liquid guide portion 14 is jointly formed by one or more porous ceramic members and one or more pieces of e-liquid absorbing cottons. In this way, the costs, mounting space, and vaporization liquid absorption and penetration efficiency are taken into consideration.

In some embodiments of the present disclosure, the heating body 2 is a heating circuit printed on the vaporization region of the second side surface 12, so that the heating body 2 is formed by printing and forms an integral structure with the liquid guide body 1. The strength of the connection between the heating body 2 and the liquid guide body 1 is high, and the two bodies can be assembled and disassembled synchronously, so that the production efficiency is high. In addition, the heating body 2 and the liquid guide body 1 are more closely fitted, and the reliability for vaporization of the vaporization liquid on the second side surface 12 is higher.

In some other embodiments of the present disclosure, the heating body 2 is a heating metal mesh arranged at the vaporization region of the second side surface 13. In this way, the heating body 2 and the liquid guide body 1 may be arranged separately, which facilitates the replacement of the heating body 2 or the liquid guide body 1, thereby improving the recycling rate, and reducing damage.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 6 and FIG. 8 , the liquid guide body 1 further includes a liquid guide portion 13, and the liquid guide portion 13 is a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm to 1.5 mm. An orthographic projection area of the liquid guide portion 13 is less than or equal to an orthographic projection area of the liquid storage portion 14 within a plane perpendicular to a direction from the first side surface 11 to the second side surface 12.

By dividing the liquid guide body 1 into a liquid guide portion 13 and a liquid storage portion 14, the liquid guide portion 13 and the liquid storage portion 14 may be made of different materials. The liquid guide portion 13 may be made of a material with high liquid absorption capacity, and the liquid storage portion 14 may be made of a high-temperature-resistant material.

The liquid guide portion 13 can lengthen a path of the liquid guide body 1 for absorption and penetration of the vaporization liquid, and increase the amount of vaporization liquid used for vaporization. The liquid guide portion 13 may be a part of the liquid guide body 1 between the first side surface 11 and a position obtained by translating the second side surface 12 to the first side surface 11 by 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm.

Because the orthographic projection area of the liquid guide portion 13 is less than the orthographic projection area of the liquid storage portion 14 in the plane perpendicular to the direction from the first side surface 11 to the second side surface 12, a step surface 15 located in the circumferential direction of the liquid guide portion 13 may be formed between the liquid guide portion 13 and the liquid storage portion 14, which can not only improve the liquid absorption efficiency of the liquid guide portion 13, but also ensure the effect and stability of vaporizing the vaporization liquid on the liquid storage portion 14 by the heating body 2.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 6 , the liquid storage portion 14 is constructed as a cuboid shape, and the liquid guide portion 13 is constructed as a cuboid shape, a frustum of trapezoidal pyramid shape, or a frustum of triangular pyramid shape. In some embodiments of the present disclosure, the arrangement of the liquid guide portion 13 is more diverse, and can be applied to different usage scenarios. The surface of the liquid guide portion 13 connected to the liquid storage portion 14 is a flat surface, which facilitates the connection between the liquid storage portion 14 and the liquid guide portion 13.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 6 and FIG. 8 , an area of the liquid absorbing region is less than or equal to an area of the vaporization region. In other words, the vaporization liquid absorbed by the liquid absorbing region can fully penetrate to at least a part of the surface of the vaporization region, which avoids excessively rapid penetration of the vaporization liquid absorbed by the liquid absorbing region and gathering in a low temperature region other than the vaporization region that causes” “e-liquid frying”, thereby improving the utilization efficiency of the vaporization liquid absorbed by the liquid absorbing region, ensuring the vaporization purity of the smoke in the vaporization cavity 42, and improving the user's inhalation experience.

In some embodiments of the present disclosure, the area of the liquid absorbing region is 9% to 95% of the area of the vaporization region. For example, the area of the liquid absorbing region may be 9%, 20%, 30%, 40%, or 50% of the area of the vaporization region, to ensure the utilization efficiency of the vaporization liquid absorbed by the liquid absorbing region. Considering the vaporization amount requirement of the vaporization region, the area of the liquid absorbing region may be set to be close to the area of the vaporization region. For example, the area of the liquid absorbing region may be 60%, 70%, 80%, 90%, or 95% of the area of the vaporization region.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 4 to FIG. 8 , the first side surface 11 is constructed as a flat surface, a polyline curved surface, an arc curved surface, or a spherical surface. When the first side surface 11 is a flat surface, the shape of the first side surface 11 is more regular, which facilitates processing and manufacturing. When the first side surface 11 is a polyline curved surface, an arc curved surface, or a spherical surface, the liquid absorbing area of the liquid absorbing region on the liquid storage portion 14 can be increased, and the liquid absorption efficiency can be improved.

In addition, the second side surface 12 is constructed as a flat surface, a polyline curved surface, an arc curved surface, or a spherical surface. When the second side surface 12 is a flat surface, the shape of the second side surface 12 is more regular, which facilitates processing and manufacturing. When the second side surface 12 is a polyline curved surface, an arc curved surface, or a spherical surface, the heating area of the vaporization region on the liquid storage portion 14 can be increased, and the vaporization efficiency can be improved, so that the vaporization volume of the vaporization liquid at the vaporization region can reach 95% to 98% of the volume of the vaporization liquid on the second side surface 12, thereby effectively avoiding the generation of vaporized condensate.

FIG. 4 and FIG. 5 are schematic diagrams of a two-dimensional arc curved surface of the second side surface 12.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 10 to FIG. 15 , the vaporization core 200 for the e-cigarette further includes a vaporization core seal member 3. The vaporization core seal member 3 is sleeved on the liquid guide body 1. The vaporization core seal member 3 has a liquid flowing opening 31, and at least a part of the first side surface 11 protrudes from the liquid flowing opening 31 to form the liquid absorbing region.

In this way, on the one hand, the vaporization core seal member 3 can fill a gap between the liquid guide body 1 and a vaporization core fixing member 5, thereby preventing the vaporization liquid in the liquid storage cavity 41 from directly leaking into the vaporization cavity 42 through the gap between the liquid guide body 1 and the vaporization core fixing member 5 without passing through the liquid guide body 1, which ensures the vaporization rate of the vaporization liquid, thereby ensuring the utilization of the vaporization liquid. On the other hand, the arrangement of the liquid flowing opening 31 can make the vaporization liquid in the liquid storage cavity 41 be in contact with the liquid guide body 1, so that the vaporization liquid flows to the liquid absorbing region through the liquid flowing opening 31.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the housing 4 is defined with a length direction (the direction indicated by the arrow A), a width direction (the direction indicated by the arrow B), and a thickness direction (the direction indicated by the arrow C). A maximum dimension of the housing 4 along the length direction is greater than a maximum dimension of the housing 4 along the width direction, and the maximum dimension of the housing 4 along the width direction is greater than or equal to a maximum dimension of the housing 4 along the thickness direction. The first side surface 11 and the second side surface 12 are arranged along the length direction of the housing 4.

In other words, the maximum dimension of the housing 4 along the thickness direction is the smallest, so that the housing 4 is flat, which is convenient for the user to put the e-cigarette into the mouth for inhalation, while the maximum dimension of the housing 4 along the length direction is the greatest. Because the first side surface 11 and the second side surface 12 are arranged along the length direction of the housing 4, the liquid storage cavity 41 and the vaporization cavity 42 are arranged on opposite sides of the liquid guide body 1 in the length direction of the housing 4. That is, the liquid storage cavity 41, the liquid guide body 1, and the vaporization cavity 42 are arranged along the length direction of the housing 4, thereby making full use of the space in the housing 4, and improving the space utilization of the housing 4.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the cartridge 100 for the e-cigarette further includes a vaporization core fixing member 5.

The vaporization core fixing member 5 is arranged inside the housing 4. The vaporization core fixing member 5 separates the liquid storage cavity 41 and the vaporization cavity 42. The vaporization core fixing member 5 has a mounting groove 51. The vaporization core 200 is arranged in the mounting groove 51. The vaporization core fixing member 5 has a communication channel 52, and the mounting groove 51 and the communication channel 52 are provided along the width direction of the housing 4. One end of the communication channel 52 is docked with the airway 43, and another end of the communication channel 52 is in communication with the vaporization cavity 42.

When the mounting groove 51 and the communication channel 52 are arranged along the width direction of the housing 4, the mounting groove 51 and the communication channel 52 can be prevented from jointly occupying a relatively large size in the thickness direction of the housing 4, thereby ensuring the thinning arrangement of the housing 4, enhancing the streamlined design effect of the housing 4, and making it convenient for the user to put the e-cigarette into the mouth for inhalation. In addition, two ends of the communication channel 52 are respectively in communication with the airway 43 and the vaporization cavity 42, and the smoke in the vaporization cavity 42 can be inhaled by the user through the communication channel 52, the airway 43, and the air outlet 45, so as to meet the user's needs.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the air inlet 44 includes an outer air inlet section 441 and an inner air inlet section 442. Both the outer air inlet section 441 and the inner air inlet section 442 extend along the length direction of the housing 4. The inner air inlet section 442 is in communication with the vaporization cavity 42, and the outer air inlet section 441 is in communication with the outside. The inner air inlet section 442 is offset by a predetermined distance relative to the outer air inlet section 441 in a direction away from the communication channel 52 along the width direction of the housing 4.

In some embodiments of the present disclosure, the airflow entering from the air inlet 44 is mixed with the vaporized air in the vaporization cavity 42, and then inhaled by the user through the communication channel 52, the airway 43 and the air outlet 45. In other words, the external airflow will first flow through the outer air inlet section 441, then flow through the inner air inlet section 442, and then flow to the communication channel 52 through the vaporization cavity 42. When the inner air inlet section 442 is offset by a predetermined distance relative to the outer air inlet section 441 in a direction away from the communication channel 52, it is equivalent to that a curved airflow path of the outer air inlet section 441, the inner air inlet section 442, and the communication channel 52 is formed, thereby increasing the length of the airflow path. On the one hand, the airflow rate can be adjusted, and on the other hand, the mixing effect of the external airflow and the vaporized airflow can be enhanced.

The specific magnitude of the predetermined distance may be adjusted according to the flow of the external airflow, the vaporization amount of the vaporized airflow, and the mixing requirement of the external airflow and the vaporized airflow.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the vaporization core 200 further includes a vaporization core seal member 3, and the vaporization core seal member 3 is sleeved on the liquid guide body 1. The vaporization core seal member 3 has a blocking portion 32 extending along the length direction of the housing 4. The blocking portion 32 extends into the vaporization cavity 42, and the blocking portion 32 is arranged at a communication position between the vaporization cavity 42 and the communication channel 52 to limit an airflow at the communication position.

In some embodiments of the present disclosure, driven by the external airflow, the vaporized air in the vaporization cavity 42 can flow to the communication channel 52, and the blocking portion 32 extends into the vaporization cavity 42. In addition, when the blocking portion 32 is arranged at the communication position between the vaporization cavity 42 and the communication channel 52, at least a part of the airflow flowing from the vaporization cavity 42 to the communication channel 52 will be blocked, which limits the flow rate of the airflow at the communication position, thereby flexibly adjusting the airflow rate.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the cartridge 100 for the e-cigarette further includes an upper seal member 6. The upper seal member 6 has an encapsulation portion 61 and a plug portion 62. An end portion of the communication channel 52 has an opening along the width direction and/or the thickness direction of the housing 4. The encapsulation portion 61 is sleeved on the vaporization core fixing member 5, and the encapsulation portion 61 forms a press-fit relationship with the vaporization core fixing member 5 and an inner wall of the housing 4. The plug portion 62 blocks the opening, and the plug portion 62 forms a press-fit relationship with the opening and the inner wall of the housing 4.

In some embodiments of the present disclosure, when the encapsulation portion 61 forms a press-fit relationship with the vaporization core fixing member 5 and the inner wall of the housing 4, that is, the encapsulation portion 61 is sandwiched between the vaporization core fixing member 5 and the inner wall of the housing 4, the effect of separating the liquid storage cavity 41 and the vaporization cavity 42 by the vaporization core fixing member 5 is improved, and the vaporization liquid in the liquid storage cavity 41 is prevented from leaking from between the vaporization core fixing member 5 and the inner wall of the housing 4 into the vaporization cavity 42.

The opening at the end portion of the communication channel 52 can facilitate the molding of the vaporization core fixing member 5, but the vaporized airflow in the communication channel 52 also has the risk of leaking into the housing 4 from the opening. When the plug portion 62 is blocked in the opening, and the plug portion 62 forms a press-fit relationship with the opening and the inner wall of the housing 4, that is, the plug portion 62 is blocked between the vaporization core fixing member 5 and the inner wall of the housing 4, the vaporized airflow in the communication channel 52 is prevented from leaking into the housing 4 from the opening of the vaporization core fixing member 5.

In addition, the upper seal member 6 further includes a first seal ring 63, and the first seal ring 63 seals the connection between the communication channel 52 and the airway 43, to ensure the sealing performance of the airflow channel in the cartridge 100.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , a vent channel 7 is arranged between the upper seal member 6 and the vaporization core fixing member 5, and the vent channel 7 is configured to communicate the vaporization cavity 42 and the liquid storage cavity 41.

In some embodiments of the present disclosure, when a pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 is less than a set pressure, because the vaporization cavity 42 is in communication with the outside through the air inlet 44, that is, the pressure in the vaporization cavity 42 is close to or equal to the atmospheric pressure, the air pressure in the liquid storage cavity 41 is kept in a state in which the liquid can flow smoothly. In this case, the vent channel 7 is in a closed state, and the liquid in the liquid storage cavity 41 can be prevented from entering the vaporization cavity 42 through the vent channel 7. When the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 is greater than or equal to the set pressure, the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 will open the vent channel 7, thereby realizing an air pressure balance between the vaporization cavity 42 and the liquid storage cavity 41.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the vaporization core fixing member 5 has a vent sinking groove 53 spaced apart from the mounting groove 51. A through hole 531 is formed on a side wall of the vent sinking groove 53, and the through hole 531 is in communication with the vaporization cavity 42. A communication groove 54 is formed on an outer circumferential surface of the vaporization core fixing member 5. An end of the communication groove 54 is in communication with the through hole 531, and another end of the communication groove 54 is in communication with the liquid storage cavity 41. The upper seal member 6 covers the through hole 531 and the communication groove 54. The upper seal member 6, the through hole 531, and the communication groove 54 forms a vent channel 7. When a pressure of the vaporization cavity 42 is greater than a pressure of the liquid storage cavity 41, the upper seal member 6 is deformed with a pressure difference to open the vent channel 7.

When the pressure of the vaporization cavity 42 is greater than the pressure of the liquid storage cavity 41, in an example, when the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 is greater than or equal to a set pressure, with the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41, the vent channel 7 is opened. In some embodiments of the present disclosure, the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 will cause the upper seal member 6 to be deformed, then the upper seal member 6 can release the blockage of the through hole 531 and the communication groove 54, and the airflow in the liquid storage cavity 41 is replenished through the vaporization cavity 42, so that the to-be-vaporized medium in the liquid storage cavity 41 can flow to the heating body 2 smoothly.

When the pressure of the vaporization cavity 42 is not greater than or slightly greater than the pressure of the liquid storage cavity 41, that is, when the pressure difference between the vaporization cavity 42 and the liquid storage cavity 41 is less than the set pressure, in this case, the pressure between the liquid storage cavity 41 and the vaporization cavity 42 is balanced, and the vent channel 7 is closed, so that the to-be-vaporized medium can flow to the heating body 2 smoothly.

Therefore, the pressure difference between the liquid storage cavity 41 and the vaporization cavity 42 can be effectively adjusted through the vent channel 7, so that the pressure of the liquid storage cavity 41 can be greater than the pressure of the vaporization cavity 42, thereby ensuring that the to-be-vaporized medium can flow to the heating body 2 smoothly and be effectively vaporized.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the housing 4 includes a main housing 46 and a lower cover 47. The air outlet 45 is formed at an end of the main housing 46, and another end of the main housing 46 is open and covered by the lower cover 47. The air inlet 44 is formed on the lower cover 47.

In some embodiments of the present disclosure, when the lower cover 47 is engaged at the opening position of the main housing 46, an accommodating space can be formed in the housing 4, and the vaporization core fixing member 5 divides the accommodating space into the liquid storage cavity 41 and the vaporization cavity 42. The air outlet 45 and the air inlet 44 are respectively formed on a side of the main housing 46 and a side of the lower cover 47 away from each other. The airflow entering from the air inlet 44 is mixed with the vaporized air in the vaporization cavity 42, and then the mixed air is inhaled by the user through the air outlet 45, so that a long-distance airflow path can be formed in the housing 4, thereby ensuring full vaporization of the vaporization liquid, and improving the user's inhalation effect.

In addition, the cartridge 100 further includes a second seal ring 92. The second seal ring 92 is sandwiched between the lower cover 47 and the inner wall at the opening position of the main housing 46 to ensure the sealing performance inside the housing 4.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the lower cover 47 includes a bottom plate 471 and a side plate 472 extending from the bottom plate 471 toward the vaporization cavity 42. A liquid absorbing member 9 covers on an inner surface of the bottom plate 471, and the liquid absorbing member 9 is arranged around the air inlet 44, or the liquid absorbing member 9 is supported on the side plate 472.

After the vaporization media such as the vaporization liquid is vaporized in the vaporization cavity 42, if the heating body 2 stops working, the vaporized air in the vaporization cavity 42 will be condensed again, and the liquid absorbing member 9 can absorb the condensed to-be-vaporized medium. In this way, the condensed to-be-vaporized medium can be prevented from leaking from the air inlet 44, thereby improving the cleanliness for use of the cartridge 100, and preventing a structure (for example, the cigarette rod of the e-cigarette) connected to the cartridge 100 from being corroded and blocked by the condensed to-be-vaporized medium.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , a conductive pin 10 extends through the lower cover 47. An end of the conductive pin 10 abuts against the heating body 2, and another end of the conductive pin 10 protrudes from an outer surface of the lower cover 47. The other end of the conductive pin 10 is electrically connected to an energy storage member in the cigarette rod of the e-cigarette, so that when the user inhales the e-cigarette, the energy storage member supplies power to the heating body 2 through the conductive pin 10, so that the heating body 2 heats the vaporization liquid, and the vaporization liquid is vaporized into an aerosol and inhaled by the user.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the cartridge 100 for the e-cigarette further includes an e-liquid-resistant and air-permeable member 8. The e-liquid-resistant and air-permeable member 8 covers the air inlet 44. When the e-liquid-resistant and air-permeable member 8 covers the air inlet 44, the vaporization liquid condensed in the vaporization cavity 42 can be prevented from flowing out from the air inlet 44 in a case of ensuring that the external airflow at the air inlet 44 enters the vaporization cavity 42 smoothly.

According to some exemplary embodiments of the present disclosure, as shown in FIG. 1 to FIG. 3 , the cartridge 100 for the e-cigarette further includes an air guide metal plate. The air guide metal plate covers the air inlet 44. The e-liquid-resistant and air-permeable member 8 may have a thin-film structure, and the e-liquid-resistant and air-permeable member 8 is mounted on a side of the air guide metal plate facing away from the air inlet 44. The air guide metal plate is configured to fix the shape of the e-liquid-resistant and air-permeable member 8.

The cartridge 100 includes a vaporization core 200. At least a part of the housing 4 is inserted into the accommodating groove. The vaporization core 200 is electrically connected to the electrical component. In some embodiments of the present disclosure, the heating body 2 in the vaporization core 200 can be electrically connected to the electrical component through the conductive pin 10. The electrical component can supply power to the heating body 2 of the vaporization core 200 through the conductive pin 10, to realize the conversion of electric energy and heat energy in the heating body 2.

When the user uses the e-cigarette, the user performs inhalation through the air outlet 45. External air enters the vaporization cavity 42 through the air inlet 44. A sensor in the e-cigarette senses an inhalation action of the user, and the electrical connection between the electrical component and the heating body 2 is turned on and power is supplied to the heating body 2, to heat and vaporize the liquid in the vaporization liquid storage cavity 41 to form smoke. The air enters the vaporization cavity 42 and drives the smoke to be inhaled by the user through the airway 43 and the air outlet 45, thereby ensuring the user's inhalation experience.

The e-cigarette according to this embodiment of the present disclosure uses the cartridge 100 according to the foregoing embodiment of the present disclosure, which can match the single-inhalation vaporization amount, thereby ensuring the amount of vapor output, and ensuring that the vaporization liquid is fully vaporized.
